Introduction
WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:

Lead from lead-based paints.

Crystalline silica from bricks, cement, and other masonry products.

Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment,
such as those dust masks that are specially designed to filter out microscopic particles.
Warning
Always wear safety glasses or goggles when operating equipment. Everyday glasses or reading glasses are
not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American
National Standards Institute (ANSI). Because there are various ways to cut and join wood, you can make
substitutions for the methods stated in this manual. We try to suggest the easiest methods possible.
However, only you know your skills with each piece of machinery. Never compromise your safety by using
a cutting method with which you are not comfortable. Instead, find an alternative approach that will yield
the same result.
Warning
These instructions assume that you are familiar with the safe operation and use of woodworking machinery
and woodworking tools, and understand the techniques used to assemble this project. If you do not qualify
for both of these criteria, STOP building this project for your own safety. Read and understand the owner’s
manual for the machinery you intend to use, take a woodworking class or visit your local library for more
information. Woodworking machinery and tools are inherently dangerous because they use sharp edges
that can and will cause serious personal injury including amputation and death. Do not underestimate the
ability of these tools and machinery to cause injury. Never operate any tool without all guards in place and
always wear approved safety glasses. For your own safety, please heed this warning.

Introduction
The remainder of the assembly instructions is divided into four sections:
Section 2 – Mockup & Fit check: in this section, all components will be checked for proper
alignment and ensure that all holes have been drilled.
Section 3 – Finishing the Body and Neck: after fit check, the components are removed from the
neck & body to allow the selected finish to be applied. This will allow you to customize your guitars’
color(s). As the finishing will likely require several coats with sanding between each coat, ensure that
the finish is completely dry.
Section 4 – Assembly: the final assembly is the next step - once the finish has been applied and
completely dried. In this section, all of the components are installed, internal wiring connected and
strings attached – your guitar will ready to go!
Section 5 – Setup: in this section, initial adjustments are made to your guitar, such as the height
of the pickups.
Again, we thank you for your purchase of a BYO Guitar and we look forward to seeing pictures of your
unique guitar! We also look forward to providing you with the guitar for your next project from our
Custom Shop where you can select the wood for the body and neck as well as customizing all of the
other components.
Let us know if your music, school, church or scouting organization would like to undertake a group
project – BYO Guitar can supply multiple kits or custom guitars.

2 Mockup and Fit Check
The following steps will ensure that the base, neck, tuners, pickups, etc. are properly aligned and that all
screw holes have been drilled.
TIP…use the large cover of the shipping box as a work area that can be easily stored
when you’re done working
2.1 Check Guitar Body & Neck mounting
holes
1. Check Neck pocket on the Body for pre-drilled
(4) mounting holes (Figure 2.1);
2. Skip to 2.2 if the holes are pre-drilled.
2.1.1
Drilling the Mounting Holes in the Guitar
Body
1. Use the neck plate as a template (#6 on material
list) to locate the mounting holes in the neck
pocket. The simplest way is to place the neck
plate into the pocket and properly position it so
it is centered in the pocket.
2. Mark the holes, center punch your marks.
P Bass Section 2 - 1 -
Figure 2.1 Body Locations
Section 2 – Mockup and Fit Check
3. Drill the holes using a 3/16” drill bit.
2.2 Checking the Mounting Holes in the Neck
1. Check neck for pre-drilled (4) mounting holes.
2. Skip to 2.3 if the holes are pre-drilled.
2.2.1 Drilling Mounting Holes in the Neck
1. Place the neck in the pocket (…you should be able to fit the neck in the neck pocket by hand).
a. Carefully clamp the neck in place – frets damage easily.
b. Using the same drill bit you drilled the holes in the body, place the bit in the hole
through the body and tap it a few times to make a mark on the neck.
2. Remove the neck from the body.
3. Determine the neck mounting hole depth.
a. Place one of the neck mounting screws through the neck plate and body into the neck
pocket.
b.
Measure the amount of the mounting screw that extends up into the neck pocket, and
mark your drill bit.
TIP…a piece of masking tape around the drill bit works great as a depth indicator.
c. Double check the depth by holding the marked drill bit to the side of the neck and be
certain the drill won’t go through the fingerboard.
4. Drill the holes in the neck with a 1/8” drill bit. Make sure you don’t drill through the
fingerboard!
2.3
Check the Neck to the Body Fit
Attach the neck so you can locate the pickguard. Use caution, the last thing you want to do is snap the
screw off in the hole!
TIP…rubbing the threads of the screw on a bar of soap or candle will help prevent the
wood from splitting
1. Insert the neck into the neck pocket and place the neck plate (with counter sunk holes facing
out) & plastic base on the body.
2. Align the mounting holes in the neck and body
3. Fasten the 4 #7 x 1 3/8” screws, but do not finial tighten them.
P Bass Section 2 - 2 -
Section 2 – Mockup and Fit Check
2.4 Fit check & alignment of the Pick Guard with Controls (item 2 on
materials list)
1. Temporarily place the pickups into their positions in the pickguard – hold in place with tape.
Place the Control Plate in the Body Control
Plate Cavity (reference Figure 2.4), while
inserting the pickguard around the neck –
ensure that the wiring is in the cavity.
2. Carefully move the Pick Guard so that the
Pick Guard contour is aligned with the
contour of the Body.
3. If the pickguard holes are not pre-drilled,
mark the holes and drill starter holes with
1/16 drill bit. Ensure all holes are predrilled.
4. Using 3/8” screws (item 4 on Material list),
temporarily attach the pickguard in 2
places.
Figure 2.4 Pickup Mounting Screws
5. Using the pickup mounting screws (#3 on material list), carefully start each screw through the
pickup into the body to a depth of approximately ¼” – ensure that each screw is perpendicular
to the body (Figure 2.4). The proper orientation of the pickups will be covered in the Assemble
section.
6. Remove the Pickguard assembly.
2.5 Fit check the Bridge
1. Ensure that the tunnel for the Bridge ground wire is
clear by inserting a small wire into the hole in the
center of the top of the Body (reference Fig. 2.1)
until it enters the Control Cavity.
2. Insert the Bridge (material list item #5) onto the
Body (reference Figure 2.1), using the supplies 7
screws.
Figure 2.6 Strap Pins
2.6 Check Strap Pins
1. Check for pre-drilled holes for the Strap Pins (item 12 on the material list), reference Figure 2.6.
2. If the holes are pre-drilled, skip to 2.7.
a. Mark the rear Strap Pin hole so that it is centered on the Neck/Bridge and the forward
Pin on the most forward point on the top of the Body (see Figure 2.6).
P Bass Section 2 - 3 -
Section 2 – Mockup and Fit Check
b. Drill starter holes with a 1/16 drill bit.
2.7 Check Tuner Alignment
Each tuner assembly consists of the tuner and hole collar. The tuners are attached to the headstock with
a small wood screws (#7 on list of materials).
1. Insert tuners (item #7 on Material List) into the
Neck Headstock from the back. Insert hole collar
the over the tuner shaft from the front. The
collars will be glued in place during assembly.
2. Ensure that the Tuner shafts are perpendicular to
the Headstock (Fig.2.8).
3. Check alignment of set screw holes (4) and tuner
base.
4. If alignment is incorrect or holes are not drilled,
mark hole locations and drill starter holes with
1/16 drill bit.
Figure 2.8 Tuner Alignment
5. Repeat for the remaining 3 tuners.
TIP… the holes may need to be widened with a peghead reamer or a round file. DO NOT
widen the holes too much—the tuners should fit snug
2.8 String Tee Position
The hole required for the installation of String Tee will be made during the guitar final assembly.

3 Finish
Before starting the finish make sure all holes are drilled for any remaining hardware (pickguard, jack
plate, strap pins etc.). This section will cover the application of several finish types, including;
1. Solid color
2. Pigmented translucent, gel stain or alcohol dye
3. Penetrating stain or water based dye
The guitar body was sanded at the factory and coated with one coat of sand and sealer. To get a good
finish, the body should be sanded with a series of sandpaper grits up to #320 grit. Apply a solid color
finish, a pigmented translucent finish (Bursts, toners, Blonde, Butterscotch Blonde etc), a gel based stain
or an alcohol based dye finish over the sanding sealer. If you plan on using a penetrating stain or water
based dye, the sanding sealer must be removed.
How you proceed will depend on the finish you would like on your guitar.
The following paragraphs outline several finishing processes, starting with the sequence for a finish type
(paragraph 3.1) followed by detailed explanation of each sequence step (paragraph 3.2).

3.2 Explanation of Sequence Steps:
3.2.1 Sanding the Body and Neck
1. Wear a NIOSH-approved respirator and ANSI-approved safety glasses when sanding wood!
2. Before starting the finish on the neck mask off the surface of the fingerboard.
P Bass Section 3 - 2 -
Section 3 - Finishing Your Guitar
3. Use a flexible sanding block with #150 grit aluminum-oxide sanding paper to sand the guitar
body until there is a consistent scratch pattern on the entire surface. Note: DO NOT round over
the neck pocket or the body cavities. When hand sanding, always sand in the same direction as
the wood grain.
4. Re-sand the entire guitar body and neck with #220 grit sanding paper and lightly round over the
outside edges of the body.
5. Wipe the guitar body and neck with a damp cloth to “raise" the wood grain.
6. Wait until the wood is dry and re-sand with #220 grit sandpaper to sand the “raised" grain
smooth.
(Note: On a maple fingerboard you can apply a clear finish to the entire neck and fingerboard. Apply
several coats and remove buildup on the frets between coats. An easy way to remove the finish buildup
on the frets is to take a nail and file a half round slot in the head about the same size as the frets. You
can then use this to easily scrape any finish build up.
If the neck has a Rosewood or Ebony fingerboard, be sure to tape off the fingerboard before applying
the finish. Behlen’s Fingerboard Oil is a great product for your fingerboard.)
3.2.2 Appling Grain Filler
Grain filler will fill in the grain and create flat surface. This is essential if you are trying to get a high gloss
finish. Oil based grain filler is recommended. We recommend using Behlen PORE-O-PAC grain filler. For
most finishes use natural colored filler. The dyes used in darker fillers may over time find their way
through the color coat.
Apply the filler by wiping across the grain. You can use a course cloth or your fingers to wipe the grain in.
After it has dried about ten to twenty minutes the excess can be removed with a cloth dampened with
mineral spirits. After about an hour repeat the process and let dry overnight. If you have removed most
of the excess with mineral spirits the remaining filler on the field of the wood can be sanded off (use
#220 again) in a few minutes. It is also a good idea at this time to reopen any of the screw holes in the
body. Use a toothpick or small drill held between your fingers to clean out any filler in the holes. The
body is now ready for a sand and sealer coating.
3.2.3 Applying Sanding Sealer
Sand and sealer is used to give the final coat a level base. It is also helpful in filling scratches which are
too deep to sand out. We recommend using Behlen Vinyl Sealer. This comes in aerosol cans and can
easily be sprayed on.
3.2.4 Solid Color Primer
The last step before applying the color coats is to apply a white primer coat. We recommend using Ohio
Valley Nitro Primer. The white background will also let you apply an opaque color coat with less paint.
Spray on two coats. When dry you may notice that the surface feels rough. Sand off the roughness with
P Bass Section 3 - 3 -
Section 3 - Finishing Your Guitar
#320 dry and respray. Sand again. If the surface now appears smooth and all grain is opaqued you are
ready for the color coat.
3.2.5 Burst and Translucent finishes
Bursts and Translucent finishes can be applied using aerosol cans of lacquer toner. Ohio Valley Nitro
and Behlen have a full line of Nitrocellulose Lacquer Toners to achieve these finishes.
3.2.6 Clear Top coats
Apply several thin coats of the finish, following the manufacturer's instructions. Multiple thin coats
usually produce a better quality finish than one heavy coat. Dry sand the entire body with #400 grit
wet/dry sandpaper after at least three coats of finish have been applied. DO NOT sand through the
finish, be careful on the edges. Use a tack cloth to remove sanding residue. Apply more finish, sanding
between coats, until the finish is the desired thickness.
3.2.7 Buff finish
When the final coat has dried at least a week, preferably a month, remove the masking. Wet sand the
finish using #600 grit wet/dry sandpaper with a sanding block, followed with #1000 grit wet/dry
sandpaper. Use a clean, absorbent rag to remove excess water. Let the guitar dry completely, then use
a tack cloth to remove all residue. Buff the finish by hand or with a buffer, starting with a medium polish
and working up to a high gloss polish.
Note: If you use a buffing machine, be careful to avoid going through the finish, especially on the edges.

After your finish has been applied and thoroughly dried, we can now assemble your guitar. In this
section we will permanently install all of the components and the wiring for the bridge and pickguard.
TIP… use a blanket or large towel on your work area to protect your guitars’ finish
4.1 Attach the Neck to the Body
1. Insert the Neck in the neck pocket. The Neck should fit snuggly into the Body neck pocket – if
there is more resistance than when the Neck and Body were fit-checked in section 2, check for
finish material build up. Carefully sand the components with fine sandpaper as required.
2. Mount the Neck plate and plastic base with 1 ¾” screws (#6 on the material list – 4 ea.),
Reminder TIP…rubbing the threads of the screw on a bar of soap or candle will help
prevent the wood from splitting
ensuring that the plate has the counter-sunk holes facing out.
3. Carefully tighten the screws – over tightening can damage the neck.
4.2 Installing Component Wiring & Installation

4.2.3 Bridge & Frame Ground Wire Installation
1. Strip approximately 1” of insulation from the Bridge ground wire. Push the wire into the tunnel
so that the exposed wire remains: bend so that the
wire is against the Body.
2. Install the Bridge with ¾” screws (#5 on the material
list – 7 ea.) ensuring that the bridge grounding wire is
in contact with the Bridge.
TIP… remove the clear
protective film from the
Pickguard & pickups
4.3 Installing the Nut
The nut holds the strings at the headstock the correct distance above the frets. It is not necessary to cut
the string notches in the nut that comes with this kit.
1. If necessary, use a chisel or razor blade to scrape any finish out of the nut slot. DO NOT remove
any wood from the nut slot.
2. Spread a thin layer of wood glue in the nut slot and center the nut in the nut slot – let dry. If
necessary, use a small clamp to ensure the nut is held in place.
TIP… wipe away the excess glue before it sets up - allow the glue to thoroughly dry

4.4 Installing the Tuners
Each tuner consists of the tuner and hole collar. The tuners are attached to the headstock with 3/8”
wood screws (refer to Section 2.7).
1. Place a tuner into the headstock hole from the back.
2. Slide collar over the tuner shaft - secure the tuner to the guitar headstock with the supplied
screws. Remove the protective film if necessary.
3. Repeat 1-3 on the remaining 3 tuners.
4. Remove the collars and place a small amount of wood glue on the inside of the tuner hole (a
toothpick might make it easier) and the collar – reinsert the collar. Repeat on the remaining
collars – let dry.
4.5 Install the Strings
Like most projects, there often several tricks that will make the assembly easier and your guitar better.
Properly stringing your guitar is just one of those tricks. Please review the
following video:
How to restring your bass guitar with John Carruthers:
https://www.youtube.com/watch?v=-8uBYIwMevA
Although the video addresses restringing a guitar, the principles and techniques will help you string your
guitar – as well as provide a visual for the stringing of your guitar.
In summary:
1. Carefully uncoil each of the strings (4), ensuring that the stings do not have a kink.
2. Adjust each tuner so that the capstan slot is parallel to the tuner shaft.
3. Run the largest diameter string (E) through the upper hole in the Bridge base plate, carefully
seating the string ball against the base plate.
4. Cut the string approximately 5” beyond the upper tuner (first) tuner. Bend the wire 90 degrees
at about ½” from the end and insert in the capstan hole of the first tuner.
5. Manually wind the string around the capstan in a clock wise direction and in a downward
direction for 2 loops (check the video). Continue to wind the string on to the capstan using the
tuner keeping tension on the string so that the winding will be tight. Continue tightening until
the string is close to pitch. The Setup section will address fine tuning.
6. Repeat steps 1 through 5 on the remaining strings (A,D & G), using the largest diameter string
during each repeat.
P Bass Section 4 - 4 -
Section 4 - Assembly
4.6 Installing the Strap Pins
Secure each strap pins (2) in the pre-drilled holes with the supplied screws (item #8 on the material list,
2ea, 1”).
4.7 Installing the String Retainer
The String Retainer is used to ensure a steep angle of the D & G strings (relative to the nut) and is placed
on the headstock between the D and G strings (the lower 2 strings as you would play the guitar).
1. Snug up the D&G strings. To protect the guitar finish while installing the String Tee, place a small
piece of tape on the headstock approximately ½” behind the A string tuner (2nd tuner from the
nut) and directly under the D&G strings.
2. Using a Spring Tee (item #13 on the material list), mark the headstock approximately ½” on the
left side of the A string tuner, between the D & G strings, #3 &4.
3. Carefully drill 1/16” starter hole in the
headstock.
4. Attach the String Tee to the headstock.

In this section, we will address the initial
setup for:
1. Adjusting the Neck (Truss Rod);
2. Adjusting the Bridge Saddle,
3. Adjusting the String Action (string
height);
4. Adjusting the Pickup heights;
5. Adjusting the Intonation.

 downloadable “musical instrument tuner” from
PerfectPitch (http://www.nch.com.au/tuner/) that will
allow visualization of string adjustments
These adjustments will provide preliminary settings from which you can fine tune the sounds to your
individual playing style. As with previous sections, references are included for additional clarification of
specific adjustments.
P Bass Section 5 - 1 -
Section 5 - Setup
String up the guitar with your desired gauge of strings – check the tuning.
5.1 Adjust the Guitar Neck: Truss Rod
The first major procedure in the setup is adjusting the neck relief. Neck relief simply refers to how much
the neck bows. The degree of bowing in the neck is a matter of personal preference and is correlated to
your playing style.
5.1.1 Adjustment Check
First, check your tuning.
Reference: …check out the following reference:
1. Put a capo at the first fret and press
the sixth string at the last fret.
2. With a feeler gauge, check the gap
between the bottom of the string and
the top of the 8th fret—you should
have about .015”.
3. If the height is correct, go to Step 5.2.

5.1.2 Adjustment
To adjust the neck relief, locate the truss rod at the neck/headstock junction. The truss rod is adjusted
with the supplied Allen wrench. Tightening the truss rod adjustment bolt will cause the neck to warp
backward (too much and the strings will buzz on the frets), and loosening it will cause it to bow forward
(giving more relief.)
1. Sight down the edge of the fingerboard
from behind the headstock, looking
toward the body of the guitar.
TIP: … do the neck adjustment in a series
of intermediate steps and re-tune your guitar before
each step – different tension on the strings changes the
adjustment of the neck
a. If the neck is too concave
(action too high), turn the truss rod nut clockwise to remove excess relief (only adjust ¼
turn at a time).
b. If the neck is too convex (strings too close to the fingerboard), turn the truss rod nut
counter-clockwise to allow the string tension to pull more relief into the neck.
2. Check tuning, then re-check the gap
with the feeler gauge and re-adjust
as needed.
5.2 Bridge Saddle
This will adjust the height of the strings
over the 12th fret. Minor adjustments are

made by raising or lowering the bridge saddles. This adjustment is a
matter of personal preference. There should be a gradual decrease in
height from the E string to the G string. Table 5.4 should be used as a
reference for adjusting the Bridge saddles.
Bridge Saddle Adjustments
5.2.1 Checking String Height
Using a calibrated metal ruler, measure the height of the string above the
12th Fret as shown in Figure 5.2.1. Check the measured height against the
desired height in Table 5.2.

1. If incorrect, adjust the string saddle height clock wise to increase
the measured distance or counterclockwise to decrease the
Table 5.2 Bridge Adjustment
measured distance. There are 2 adjustments on each saddle that
Heights
should be adjusted simultaneously so that the saddle remains level.
2. Repeat on the next string until all strings have been adjusted.
5.3
Nut Action
Setting the string action that is right for you starts at the nut. The slots
should already be close, but you might want to make some
adjustments. The adjustment of the nut height requires special files
and can be performed at a future date. If you are unsure how this
action will impact your specific playing style, we suggest that you
measure and record the height for all strings in Table 5.3. Should you
decide to make this adjustment in the future, you will know which
strings need to be adjusted and by how much.
5.3.1 Measurement
1. Using a .022 feeler gauge, measure &
record the space between the first
fret and the bottom E string – the
gauge should be a snug fit if spacing
is correct.
2. Repeat on A, D & G strings.

(Step 3 of 4): by John Caruuthers
5.3.2 Nut Adjustment
If the gap is wider than .022”, the slot needs to be deepened.
1. Detune the tuner for the string you are working on so that it
can be removed from the nut.

2. Using a small file or round needle file, carefully deepen the nut slot. Make sure when you
deepen the nut slot, the file is angled down toward the headstock. This will ensure the string
sits on the edge of the nut closest to the fretboard.
3. The slot adjustment will take several iterations to ensure the depth is correct. Replace the string
in the nut, retune using the tuner and check the spacing.
4. Repeat steps 1-3 until the depth is correct.
5. Repeat steps 1-4 for the remaining 3 strings.
5.4 Pickup Height
There are two adjustments that are required for the P Bass guitar: treble adjustment of the G string, and
bass adjustment of the E string. Again the final adjustment height is your personal choice – the following
adjustments will be a place to start. Determining the best combination of tone and volume will require
some experimentation.
5.4.1 Treble (G string) adjustment
1. Measure the distance from the bottom of the G string (furthest from the top of the guitar) to
the top of the pickup closest to the Bridge: correct measurement is 1/8”.
2. If correct, go to step 5.5.2
3. Adjust the 2 screws on the G string pickup for the 1/8” measurement. Push on the pickup to
ensure that the pickup springs are free.
5.4.2 Bass (E string) adjustment
4. Measure the distance from the bottom of the E string (closest to the top of the guitar) to the top
of the pickup closest to the Neck: correct measurement is 1/8”.
5. If correct, go to step 5.6.
6. Adjust the 2 screws on the E string pickup for the 1/8” measurement. Push on the pickup to
ensure that the pickup springs are free.
5.5
Intonation
Intonation adjustments should be made
after all of the above have been
accomplished. Again, intonation is a personal
choice and we suggest reviewing the
adjacent reference before proceeding.
1. Turn the volume & tone controls to
maximum.

Section 5 - Setup
2. Check tuning. Check each string at the 12th fret, harmonic to fretted note (make sure you are
depressing the string evenly to the fret, not the fingerboard).
3. If sharp, lengthen the string by adjusting the saddle back. If flat, shorten the string by moving
the saddle forward.
5.6 String Lubrication
Lubricate the contact points of a string's travel to ensure tuning stability and reduce string breakage.
Lubricate:
1. String/saddle contact points on the Bridge with a light machine oil (…such as “3-in-1 oil” because
it contains anti-rust and anti-corrosive properties) every time you change strings.
2. String trees should also be lubricated; a small amount of lip balm applied with a toothpick works
well.
5.7 …Other Hints
There are a few other things that you can do to optimize your tuning stability:
1. Each time you play your guitar, before you do your final tuning, play for a few minutes to allow
the strings to warm up. Metal expands when warm and contracts when cool. After you've
played a few riffs, you can then do your final tuning;
2. Wipe the strings, neck and bridge with a lint-free cloth after playing;
3.
When transporting or storing your guitar, even for short periods, avoid leaving it anyplace you
wouldn't feel comfortable yourself.
Remember, guitars are tempered instruments! Re-tune, play and make further adjustments as needed.
